A large tree, with short spreading or long pendulous branches^nd scaly dark brown trunk, reaching a height of 120 and a diam-eter of 11 feet. It occurs in rich moistsoil from southern Newfoundland tothe northern shores of Lake Superior and the eastern slope of theRocky mountains, south to Florida, and west to Dakota, central-Nebraska, Indian Territory, and Texas ; reaching its best develop-ment in the northeastern United States, In this State, where it reaches an average height of 60 to 70 anddiameter of 4 to 5 feet, it occurs abundantly in most of the swamps. Distribution of the AMERICAN(Ulmus americana, L^ -of the coastal plain and extends westward as far as Guilfordand Mecklenburg counties. (Fig. 13.) It is smaller and muchless common toward its western limit. WINGED ELM. 7T Seed is borne generally every year in abundance, and youngplants are common in damp open places. The American elm doesnot sprout readily from the stump. A larva of a longicorn beetle, Saperda tridentata, Oliver, loosensthe inner bark and channels the surface of the wood so as fre-quently to kill the tree. The American elm also suffers severelyfrom canker-worms, Paleacrita vernata. Peck, and Eugenia sub-signaria, Huebner, and the imported elm-leaf beetle, Galerucascanthoraelsena, Schrank, all of which feed upon and destroy thefoliage. The leaves are usually smaller and less rough than those of theslippery elm. The small greenish-brown flowers are in numerous,lateral clusters and appear early iti spring. The flattened oval
